Abstract

The utility model provides a radiator for LED lamp, the radiator comprises a radiator body, be hollow body in the middle of the body, be equipped with the fin on the radiator body, the wall connection of fin and cavity body, the fin be the Y type, the fin include first fin, second fin, third fin. The fin design of this radiator is favorable to the circulation of air between the fin for the Y type, and the simple structure easily production has reduced the heat dissipation volume under same radiating efficiency.

Description

A kind of heat radiator for LED lamp

Technical field

This utility model belongs to LED technical field, is specifically related to a kind of heat radiator for LED lamp.

Background technology

LED illumination has three advantages main: energy-saving and environmental protection, green illumination.This LED is become in the world today one of light source of new generation substituting conventional light source.During LED operation, owing to being PN junction work, LED chip has fever phenomenon and produces, so heat dissipation design must be carried out for this situation.The heat produced after LED illumination lamp luminescence is mainly conducted by LED-baseplate and the heat abstractor being arranged on LED.And good heat dissipation design can significantly extend the service life of LED, therefore heat dissipation design plays vital effect to the performance of LED light source.

The method solving heat dissipation problem mainly has two kinds: (1) improves the quality of lamp interior LED chip, improves the internal quantum efficiency of chip light emitting, thus improve the luminous efficiency of chip under same operating current；(2) improve the heat dissipation design outside light fixture, configure rational heat abstractor, to accelerate radiation processes.

Utility model content

Utility model purpose: the LED fin of a kind of perfect heat-dissipating is provided.

Technical scheme: a kind of radiator for LED light device, including radiator body, it it is the body of hollow in the middle of described body, described radiator body is provided with fin, described fin is connected with the outer wall of hollow tube, described fin is Y type, and described fin includes the first fin, the second fin, the 3rd fin.The fin of Y type adds area of dissipation in the case of not increasing heat dissipating mass, is conducive to improving radiating efficiency.

Preferably the first described fin is provided with heat radiation projection as of the present utility model, and heat radiation is protruding also in the case of not affecting air circulation, increases area of dissipation.

As of the present utility model preferably, the second described fin and the 3rd fin undulate respectively, corrugated fin has more preferable radiating effect than the fin of plane.

As of the present utility model preferably, described heat radiation projection prominent place plane 1～3mm.

As of the present utility model preferably, described first fin is in " it " font.

As of the present utility model preferably, the angle of the first fin and tube wall is 8～15 °, and the fin of Y type can be arranged on the body of hollow with the angle of inclination of 8～15 °, thus strengthens ventilation effect.

As of the present utility model preferably, described first fin, the second fin, the 3rd fin length ratio for 1:2:2, increase by second and the length of fin the 3rd fin, be effectively increased area of dissipation.

Beneficial effect:

This utility model provides a kind of radiator for LED light device, and the heat sink design of this radiator is Y type, is conducive to the air circulation between a fin, and simple in construction is readily produced, and reduces heat dissipating mass under same radiating efficiency.

Detailed description of the invention

According to following embodiment, the present invention be may be better understood.But, as it will be easily appreciated by one skilled in the art that the content described by embodiment is merely to illustrate the present invention, and should be also without limitation on the present invention described in detail in claims.

In Fig. 1～Fig. 3,1 is the body of hollow, and 2 is fin, and 3 is heat radiation projection, and 21 is the first fin, and 22 is the second fin, and 23 is the 3rd fin.

In Fig. 1, a kind of radiator for LED light device, including radiator body, it it is the body 1 of hollow in the middle of described body, described radiator body is provided with fin 2, described fin is connected with the outer wall of hollow tube 1, and described fin 2 is in Y type, and described fin includes first fin the 21, second fin the 22, the 3rd fin 23.

The first described fin 21 is provided with heat radiation protruding 3, and heat radiation protruding 3, also in the case of not affecting air circulation, increases area of dissipation.

The second described fin 22 and the 3rd fin 23 undulate respectively, corrugated fin has more preferable radiating effect than the fin of plane.

Described heat radiation protruding 3 highlights place plane 1～3mm.

Described first fin 21, in " it " font, the first fin of "the" shape can also be uniformly distributed heat radiation protruding 3.

First fin 21 is 8～15 ° with the angle of tube wall, and the fin of Y type can be arranged on the body of hollow with the angle of inclination of 8～15 °, thus strengthens ventilation effect.
